Effect of troposphere delay on measurement of high dynamic receiver

Dealing with Large acceleration and jerk of carrier is necessary for High dynamic navigation receiver which has a great practical value on applying directly to the military and also has a higher requirements for the measurement accuracy. In this paper, the characteristics of different troposphere model is analyzed, the characteristics of high dynamic navigation receiver and the basic formula of the positioning speed measurement algorithm are also analyzed. The Hopfield troposphere delay model is applied to the actual high dynamic receiver, and mede comparisons with the measuring result of the old troposphere delay model. Test results show that through using the Hopfield model , the positional accuracy is improved, and the error problem which generated by the influence of the troposphere delay is eliminated.
